Y Leners Patent No. 61,716; daad February 5,1867.

IMPROVEMENT IN. GHURNS.

TO ALL WHOM IT MAY OONCERN:

Be it known that I, DE'WITTCLOUGH, of the cit)y of Auburn, in Cayuga county, New York, have invented' a new and`improved Mode of Constructing the Common Dash Churn l; 'and I do hereby` declare the following to be a full, clear, and exact descriptionl of-the same, reference being had to the accompanying drawings, making a part of this'speciication, and to the letters of reference marked thereon.

The object of this invention is' to prevent the cream from working up through the Atop of Athe churn in the process of churning, and at the same time to supply all the air requisite to make the butter; and in order'that others skilled inthe art may know how to make and use my invention, I will proceed to describe its construction Vand inode of operation. A A

Figure l isaperspective view of the device used for theabove purpose, in which A represents the vposition of the dash-rod; B the top of the air-chamber 'C- the top of the churn, and D andE the air-chamber portions ofthe, form which is represented in dotted lines, they being behind the top of the churn YC. Y

Figure 2 is a vertical cross-section taken through the centre of fig. 1. y

The dotted lines. showing the place occupied by` the churn A dash-rod; B top ofairchamber; D and E air-chamber, and F the inside thereof; 2'3 4 5 6 are openings into said chamber. 1 and 6 are above the top of the -`,churn C, 2 3 4 5 are below and communicate with the inside ofthe churn. The holes'l 2 6 are airholes; and the holes 3 and 4 are dripping-holes .to allow the cream which is brought up from below into the air-chamber F to drip immediately back into the churn. -l As the davsh-rod is`thrust down, a body'of atmospheric air, equalin content to the dosh-rod', passes into the holes 2 and 5, into .theair-chamber F, and from thence outv of the holes 1 and 6, and when the dash-rod is lifted a. reverse action takes place, and air in sulicient quantities is allowed to enter the churn for all practical purposes. The holes 1 2 Sand 6 being horizontal, and-the air-tube vertical, if the holes are made of suitable size no particle of cream or milk can escape from the bodyl of the churn. The nature of my invention consists in having a. vertical air-chamber,.with horizontal openings therein, to altw of a. free ingress and egress of the air to compensate for the action' of the' dash-rod.

' Having above described the construction and mode'of operating my invention', what I claim as new, and wish to secure by Letters Patent, is-

J\'.lhe vertical air-chamber F, with the horizontal openings 1 2 5 6, as above set forth.
